Many thanks for the response and advice. The iLand app is smart enough to force warning lights on. All of them worked except for ABS, TC and the Hill decent warning in the bottom left.
Another key detail that I neglected to mention is that none of these systems seem to work at all. Wheel spin over obstacles, and abs does not kick during hard braking.
The iLand is reading codes related to shuttle valve, and pump relay open circuit. I replaced the shuttle valve with a new one, cleared the code and it has returned.
Hoping to find someone in Los Angeles with a Nanocom to see if I can get closer to the answer before digging in.
